3.7 System Cooling
Fans
The chassis contains six 6-cm high-performance fans. Fan speed is controlled by the BMC
depending on the system temperature. If a fan fails, the remaining fans will ramp up to full
speed. The system will continue to run with a failed fan, although it may shut down if the
heat gets too great. Replace any failed fan at your earliest convenience with the same model.
Failed fans can be identified through the BMC.
Changing a System Fan
1. Using the handle, pull the drawer with the failed fan from the chassis.
2.
Push the replacement fan assembly drawer firmly into the housing.
3. Check that the fan is working properly and that the alert LED on the control panel turns
off.
